3 Claims.

My invention relates to a method for manufacturing fruit and vegetable slicers.

This invention particularly has reference to a method of forming a slicer by severing portions of a plate to form apertures, and depressing portions of the plate around the apertures to form beveled cutting edges.

Referring to the drawing: Figure 1 is a top plan view of the finished article looking at the plate from the side on which the depressions have been forced;

Figure 2 is a section on the line 22 thereof; Figure 3 is a View of the back thereof; Figure 4 is an enlarged portion of Figure 2 showing in detail the bafiie edges of the depressed portions;

Figure 5 is a bottom plan view of the punch; Figure 6 is a top plan view of the die; and Figure '7 is a section through the punch, the metal being formed, and the die.

Referring to the drawing in detail, the punch l is provided with a piercing punch 2 having shearing edges 3, which first pierces a hole 4 in the metal sheet 5. Associated with this punch 2 is a laterally-extending, tapered shoulder 6, of less depth than the punch, which immediately starts to depress a portion of the sheet 5, as at 7, and because of the draw of the depression, the upper edge 8 adjacent the hole 4 of the depressed portion 7 is drawn back so that a beveled cutting surface 9 is formed on one side, While, on the other side of the opening 4 the non-depressed portion of the sheet is aligned and a vertical face 10 is formed at right angles to the sheet.

The shoulder 11 holds the plate 5 adjacent the edge 10 against the supporting die 12, which is provided with a recess 13 having an arcuate end adjacent the opening 14 for receiving the depressed portion 7 of the plate 5.

The shearing plug 2 enters the opening 14 so that the shoulder 6 may press the depressed portion '7 into the recess 13, as at 15.

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varying conditions and uses.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a method of forming a slicer, severing and removing a portion of a plate to form a round aperture, depressing a portion of the metal around the severed portion, and continuing the depression to a point where the upper edge adjacent the depressed portion where a part has been severed from the sheet is drawn back to form a beveled edge.

2. In a method of forming a slicer, severing a portion of a plate to form an aperture, depressing a portion of the metal around the severed portion, continuing the depressing to a point where the upper edge adjacent the depressed portion where a part has been severed from the sheet is drawn back to form a beveled edge, and holding the remainder of the sheet adjacent the severed portion while depressing and drawing back is taking place.

3. In a method of forming a slicer with depressed beveled edges adjacent apertures, severing a portion of a sheet to form an aperture, depressing a portion of the sheet adjacent the aperture, and simultaneously drawing back the upper edge of the sheet adjacent the aperture to form a beveled depressed edge, and aligning the nondepressed portion of the sheet adjacent the aperture to form a right angle edge.
